DETAILED DESCRIPTION

Examples will be described in detail herein, with the illustrationsthereof represented in the drawings. When the following descriptionsinvolve the drawings, like numerals in different drawings refer to likeor similar elements unless otherwise indicated. The embodimentsdescribed in the following examples do not represent all embodimentsconsistent with the present disclosure. Rather, they are merely examplesof apparatuses and methods consistent with some aspects of the presentdisclosure as detailed in the appended claims.

For example, a logical resource element corresponds to a physicalresource element bundle including one or more physical resourceelements. In the related art, an interleaving is performed by a functionas follows:

f(j)=(rC+c+n_(shift))mod(N ^(CORESET) /L),

C=┌N ^(CORESET)/(LR)┐,

where j refers to a sequence number of the physical resource elementbundle, c refers to a row coordinate of an interleaving matrixcorresponding to the function, r refers to a column coordinate of theinterleaving matrix, N^(CORESET) refers to an actual quantity ofphysical resource elements, L refers to a quantity of physical resourceelements included in one physical resource element bundle, R andn_(shift) refer to preset parameters, and mod represents an operationfor taking a remainder.

According to a manner in the related art, in some cases, one physicalresource element bundle may correspond to multiple logical resourceelements. In this way, a mapping result obtained based on such kind ofcorrespondence is unreasonable, which may cause a problem duringresource transmission.

For example, assuming N^(CORESET)=48, L=6, R=6, thenC=┌N^(CORESET)/(LR)┐=2 can be obtained, and the values of c are 0 and 1.Assuming quantity of physical resource elements corresponding to eachlogical resource element is N=6, then a quantity of physical resourceelement bundles corresponding to each logical resource element is 6/6=1.

When c=0, a value range of j is 0 to 5, and a sequence number of aninterleaved physical resource element bundle can be obtained as: f(0)=0;f(1)=2; f(2)=4; f(3)=6; f(4)=0; and f(5)=2. When c=1, the value range ofj is 6 and 7, and a sequence number of an interleaved physical resourceelement bundle can be obtained as: f(6)=1 and f(7)=3.

Since each logical resource element corresponds to one physical resourceelement bundle, it can be concluded from the above results that thezeroth logical resource element corresponds to the zeroth physicalresource element bundle, the first logical resource element correspondsto the second physical resource element bundle, the second logicalresource element corresponds to the fourth physical resource elementbundle, the third logical resource element corresponds to the sixthphysical resource element bundle, the fourth logical resource elementcorresponds to the zeroth physical resource element bundle, the fifthlogical resource element corresponds to the second physical resourceelement bundle, the sixth logical resource element corresponds to thefirst physical resource element bundle, and the seventh logical resourceelement corresponds to the third physical resource element bundle. Itcan be seen that the zeroth physical resource element bundle correspondsto two logical resource elements, and the second physical resourceelement bundle corresponds to two logical resource elements. Further,the fifth and seventh physical resource element bundle do not correspondto any logical resource element.

To avoid the above situation, a method adopted in the related art is tolimit the value of C to be an integer, i.e., N^(CORESET) is an integermultiple of L×R. However, due to the limit to the value of C, theflexibility of resource configuration is relatively decreased.

FIG. 1 is a schematic flowchart illustrating an interleaved mappingmethod according to an example of the present disclosure. Theinterleaved mapping method shown in the example can be applicable touser equipment, such as a mobile phone, a tablet computer, and so on,and can also be applicable to a base station, such as a 4G basestations, a 5G base station, and so on.

As shown in FIG. 1, the interleaved mapping method can include thefollowing steps.

At step S1, a virtual sequence of first physical resource elementbundles is interleaved according to an interleaving function. The firstphysical resource element bundles include actual physical resourceelement bundles and one or more virtual physical resource elementbundles.

In an example, the virtual sequence refers to that the first physicalresource element bundles are sorted according to a preset mode (forexample, sorting according to positions in the time domain first, andthen sorting according to positions in the frequency domain; or sortingaccording to positions in the frequency domain first, and then sortingaccording to positions in the time domain), and a total quantity of thesorted first physical resource element bundles may be greater than anactual quantity of actual physical resource element bundles, where afirst physical resource element bundle with a sequence number greaterthan the actual quantity of physical resource element bundles belongs toa virtual physical resource element bundle.

Interleaving the virtual sequence refers to reordering the virtualsequence according to the interleaving function. For example,substituting a virtual sequence number of the virtual sequence into theinterleaving function can obtain a reordered interleaving sequencenumber.

It should be noted that, in the examples of the present disclosure, theactual quantity of the actual physical resource element bundles refersto a quantity of physical resource element bundles in physical resourceelements which are allocated for a channel by a communication system.For example, assuming N^(CORESET)=48 and L=6, then the actual quantityof the actual physical resource element bundles is 8.

At step S2, a physical resource element bundle in the interleaved firstphysical resource element bundles without any corresponding actualphysical resource element bundle is marked as an invalid physicalresource element bundle.

In an example, since a first physical resource element bundle with asequence number greater than the actual quantity of the actual physicalresource element bundles belongs to a virtual physical resource elementbundle, after the virtual sequence is interleaved according to theinterleaving function, one or more invalid physical resource elementbundles still exist in the interleaved first physical resource elementbundles. For example, interleaving sequence numbers of the interleavedfirst physical resource element bundles can be determined, and aphysical resource element bundle corresponding to an interleavingsequence number greater than the actual quantity of the actual physicalresource element bundles can be marked as the invalid physical resourceelement bundle.

At step S3, a first correspondence of the valid physical resourceelement bundles in the interleaved first physical resource elementbundles with respect to an actual sequence of the actual physicalresource element bundles is determined.

In an example, the virtual sequence numbers corresponding to the validphysical resource element bundles in the interleaved first physicalresource element bundles are different, and the valid physical resourceelement bundles can be further processed according to the virtualsequence number from small to large, so as to obtain the actual sequenceof the actual physical resource element bundles. An actual sequencenumber of the actual sequence and an interleaving sequence number of thevalid physical resource element bundles can represent the firstcorrespondence of the valid physical resource element bundles in theinterleaved first physical resource element bundles with respect to theactual sequence.

At step S4, a mapping relationship between logical resource elements andthe actual physical resource element bundles is determined based on thefirst correspondence and a second correspondence of the logical resourceelements with respect to the actual sequence.

In an example, based on a quantity of physical resource elementsincluded in one logical resource element and a quantity of physicalresource elements included in one physical resource element bundle, aquantity of physical resource element bundles included in one logicalresource element can be determined. That is, a quantity of physicalresource element bundles corresponding to each logical resource elementcan be determined. For example, each logical resource elementcorresponds to two physical resource element bundles, then the secondcorrespondence is that each logical resource element corresponds to twoactual sequence numbers in the actual sequence.

Since the first correspondence can represent a relationship between theactual sequence and the valid physical resource element bundles in theinterleaved first physical resource element bundles, and the secondcorrespondence can represent a relationship between the actual sequenceand the logical resource elements, according to the first correspondenceand the second correspondence, the mapping relationship between thelogical resource elements and the valid physical resource elementbundles, i.e., the actual physical resource element bundles, can bedetermined.

The first physical resource element bundles are interleaved, and thenthe physical resource element bundle in the interleaved first physicalresource element bundles not corresponding to any actual physicalresource element bundle is marked as invalid. In the process ofestablishing the mapping relationship between a logical resource elementand an actual physical resource element bundle, it can avoid the logicalresource element mapping to a physical resource element bundle with aninvalid sequence number, and different logical resource elements willnot be mapped to the same physical resource element, thereby ensuringthe reasonability of the mapping relationship, and ensuring thatresource transmission will not be problematic. Furthermore, a value of aparameter in the interleaving function is not limited, thereby ensuringhigh flexibility in resource configuration.

FIG. 2 is a schematic flowchart illustrating a process of marking aphysical resource element bundle in the interleaved first physicalresource element bundles without any corresponding actual physicalresource element bundle as an invalid physical resource element bundleaccording to an example of the present disclosure. As shown in FIG. 2,marking the physical resource element bundle in the interleaved firstphysical resource element bundles without any corresponding actualphysical resource element bundle as the invalid physical resourceelement bundle includes the followings.

At step S21, a quantity of actual physical resource element bundlesincluded in the first resource element bundles is determined.

At step S22, according to a relationship between an interleavingsequence number of an interleaved physical resource element bundle andthe quantity, the invalid physical resource element bundle in theinterleaved first physical resource element bundles that does notcorrespond to any actual physical resource element bundle is determined.

At step S23, the invalid physical resource element bundle is marked.

In an example, in an interleaving function, the virtual sequence numberof the virtual sequence can be obtained through a specific operation,and this operation may include a rounding (for example, rounding up)operation. Since a value obtained by the rounding operation may notequal to an unrounded value, it may cause a value range of the virtualsequence number may be different from a value range of the actualsequence number, such that the virtual sequence number may be greaterthan the actual quantity of the actual physical resource elementbundles. A physical resource element bundle with a virtual sequencenumber greater than the actual quantity of the actual physical resourceelement bundles, i.e., a virtual physical resource element bundle, doesnot actually exist, so such physical resource element bundle can betaken as a virtual physical resource element bundle. AssumingN^(CORESET)=48, and L=6, R=6, then C=┌N^(CORESET)/(LR)┐=2 can beobtained. In this case, the value range of the virtual sequence numbermay be from 0 to 11, while the actual quantity of the actual physicalresource element bundles is 8. Thus, a physical resource element bundlewith a virtual sequence number from 8 to 11 can be taken as the virtualphysical resource element bundle.

In some embodiments, the interleaving function can bef(j)=(rC+c+n_(shift))mod(CR).

Where, j represents a virtual sequence number of the virtual sequence,f(j) refers to an interleaving sequence number after interleaving thevirtual sequence number, j=cR+r, r=0, 1, . . . , R−1, c=0, 1, . . . ,C−1, C=┌N^(CORESET)/(LR)┐, c refers to a row coordinate of aninterleaving matrix corresponding to the function, r refers to a columncoordinate of the interleaving matrix, N^(CORESET)refers to an actualquantity of physical resource elements, L refers to a quantity ofphysical resource elements included in one physical resource elementbundle, R refers to a first preset parameter, n_(shift) refers to asecond preset parameter, mod represents an operation for taking aremainder.

Marking the invalid physical resource element bundle in the interleavedfirst physical resource element bundles that does not correspond to anyactual physical resource element bundle includes:

-   if f(j) is greater than N^(CORESET)/L−1, f(j) is marked as invalid.

If f (j) is less than or equal to N^(CORESET)/L−1, f(j) is taken as avalid physical resource element bundle.

In an example, N^(CORESET) refers to the actual quantity of physicalresource elements, and each physical resource element bundle includes Lphysical resource elements, then N^(CORESET)/L refers to the actualquantity of actual physical resource element bundles. If theinterleaving sequence number f(j) and a sequence number of the actualphysical resource element bundles start from 0, the maximum sequencenumber of the actual physical resource element bundles isN^(CORESET)/L−1. That is, when f(j) corresponds to a physical resourceelement bundle with a sequence number greater than N^(CORESET)/L−1, suchkind of f(j) is an invalid physical resource element bundle, which canbe marked as invalid.

FIG. 3 is a schematic flowchart illustrating a process of determining afirst correspondence of the valid physical resource element bundles inthe interleaved first physical resource element bundles with respect toan actual sequence of the actual physical resource element bundlesaccording to an example of the present disclosure. As shown in FIG. 3,determining the first correspondence between the actual sequence of theactual physical resource element bundles and the valid physical resourceelement bundles in the interleaved first physical resource elementbundles includes the followings.

At step S31, a first correspondence g(m)=f(j) between an actual sequencenumber m and a virtual sequence number j is determined, where, if f(j)is valid, mark g(m)=f(j), and if f(j) is invalid, a value of j isincreased until f(j) is valid, mark g(m)=f( .j)

In an example, by determining the first correspondence between theactual sequence number and the virtual sequence number, the interleavingsequence number f(j) corresponding to a valid physical resource elementmay be sorted according to a change order of the actual sequence numbersm from small to large, so as to determine a relationship between alogical resource element and the interleaving sequence number f(j)according to a relationship between the logical resource element and theactual sequence number. Further, a mapping relationship between thelogical resource element and a valid physical resource element bundlecorresponding to the interleaving sequence number f(j), i.e., an actualphysical resource element bundle, is determined based on therelationship between the logical resource element and the interleavingsequence number f(j).

FIG. 4 is schematic flowchart illustrating a process of determining amapping relationship between logical resource elements and actualphysical resource element bundles based on the first correspondence anda second correspondence of the logical resource elements with respect tothe actual sequence according to an example of the present disclosure.As shown in FIG. 4, determining the mapping relationship between thelogical resource elements and the actual physical resource elementbundles based on the first correspondence and the second correspondencebetween the logical resource elements and the actual sequence includesthe followings.

At step S41, the second correspondence between a logical resourceelement and an actual sequence number is determined based on an order ofthe actual sequence numbers and a quantity of physical resource elementbundles included in one logical resource element.

At step S42, the mapping relationship between the logical resourceelements and the valid physical resource element bundles is determinedbased on the first correspondence and the second correspondence.

In an example, each step in the foregoing example may be described byusing codes as followings:

%% for c=0:C−1 for r=0:R−1 j=cR+r; f(j)=(r*C+c) mod (C*R) if f(j) >N^(CORESET) / L − 1 f(j)=NULL; end end end %% delete portion of NULLm=0; for j=0: C*R−1 if f(j)!=NULL & m< N^(CORESET) / L − 1 g(m)=f(j)m++; end end %%

NULL refers to invalid. The virtual sequence number and the actualsequence number only indicate an order (physical resource elementbundles can be sorted in a preset manner, for example, sorted accordingto an order of symbols in the time domain corresponding to the physicalresource element bundles), the virtual sequence number j refers to asequence number of the first physical resource element bundles beforeinterleaving. And the so-called virtual means that the maximum value ofj may be greater than the actual quantity of the actual physicalresource element bundles. The actual sequence number m refers to asequence number of an actual physical resource element bundle mappedwith a logical resource element.

The interleaved mapping method described in the foregoing examples willbe exemplarily described in the following two examples.

In an example, for example, assuming that N^(CORESET)=48, L=6, R=6, andthe quantity N of physical resource elements corresponding to eachlogical resource element equals 6, then C=┌N^(CORESET)/(LR)┐=2, thevalue range of j is 0 to 11. Then f(j) can be calculated asf(j)=(rC+c+n_(shift))mod(CR), and codes show as followings:

for c=0:1 for r=0:5 j=cR+r; f(j)=(r*C+c) mod (C*R) end end

Next an invalid f(j) can be determined, and codes show as followings:

if f(j) > N^(CORESET) / L − 1 f(j)=NULL; end

Thus, it can be obtained that f(0)=0; f(1)=2; f(2)=4; f(3)=6; f(4)=NULL;f(5)=NULL; f(6)=1; f(7)=3; f(8)=5; f(9)=7; f(8)=NULL; f(9)=NULL;f(10)=NULL; and f(11)=NULL.

Then the first corresponding relationship between an actual sequencenumber m and a virtual sequence number j can be determined. The valuerange of m is from 0 to N^(CORESET)/L−1, and codes show as followings:

m=0; for j=0: C*R−1 if f(j)!=NULL & m< N^(CORESET) / L − 1 g(m)=f(j)m++; end end

It can be obtained that g(0)=0; g(1)=2; g(2)=4; g(3)=6; g(4)=1; g(5)=3;g(6)=5; g(7)=7. That is, the actual sequence number 0 corresponds to thezeroth physical resource element bundle, the actual sequence number 1corresponds to the second physical resource element bundle, the actualsequence number 2 corresponds to the fourth physical resource elementbundle, the actual sequence number 3 corresponds to the sixth physicalresource element bundle, the actual sequence number 4 corresponds to thefirst physical resource element bundle, the actual sequence number 5corresponds to the third physical resource element bundle, the actualsequence number 6 corresponds to the fifth physical resource elementbundle, and the actual sequence number 7 corresponds to the seventhphysical resource element bundle. These physical resource elementbundles are all actual physical resource element bundles.

Since the number of physical resource element bundles corresponding toeach logical resource element is N/L=1, the zeroth logical resourceelement corresponds to the zeroth physical resource element bundle, thefirst logical resource element corresponds to the second physicalresource element bundle, the second logical resource element correspondsto the fourth physical resource element bundle, the third logicalresource element corresponds to the sixth physical resource elementbundle, the fourth logical resource element corresponds to the firstphysical resource element bundle, the fifth logical resource elementcorresponds to the third physical resource element bundle, the sixthlogical resource element corresponds to the fifth physical resourceelement bundle, and the seventh logical resource element corresponds tothe seventh physical resource element bundle. These physical resourceelement bundles are all actual physical resource element bundles.

Thus, on the basis of establishing the mapping relationship between thelogical resource element and the physical resource element bundle, it isensured that different logical resource elements will not be mapped tothe same physical resource element.

In an example, for example, assuming that N^(CORESET)=48 , L=3, R=6, andthe quantity N of physical resource elements corresponding to eachlogical resource element equals 6, then C=┌N^(CORESET)/(LR)┐=3, thevalue range of j is 0 to 17. Then f (j) can be calculated asf(j)=(rC+c+n_(shift))mod(CR), and codes show as followings:

for c=0:2 for r=0:5 j=cR+r; f(j)=(r*C+c) mod (C*R) end end

Next an invalid f(j) can be determined, and codes show as followings:

if f(j)> N^(CORESET) / L − 1 f(j)=NULL; end

Thus, it can be obtained that f(0)=0; f(1)=3; f(2)=6; f(3)=9; f(4)=12;45)=15; f(6)=1; f(7)=4; f(8)=7; f(9)=10; f(10)=13; f(11)=NULL; f(12)=2;f(13)=5; f(14)=8; f(15)=11; f(16)=14; and f(17)=NULL.

Then the first corresponding relationship between an actual sequencenumber m and a virtual sequence number j can be determined. The valuerange of m is from 0 to N^(CORESET)/L−1, and codes show as followings:

m=0; for j=0: C*R−1 if f(j)!=NULL & n< N^(CORESET) / L − 1 g(m)=f(j)m++; end end

It can be obtained that g(0)=0; g(1)=3; g(2)=6; g(3)=9; g(4)=12;g(5)=15; g(6)=1; g(7)=4; g(8)=7; g(9)=10; g(10)=13; g(11)=2; g(12)=5;g(13)=8; g(14)=11; and g(15)=14. That is, the actual sequence number 0corresponds to the zeroth physical resource element bundle, the actualsequence number 1 corresponds to the third physical resource elementbundle, the actual sequence number 2 corresponds to the sixth physicalresource element bundle, the actual sequence number 3 corresponds to theninth physical resource element bundle, the actual sequence number 4corresponds to the twelfth physical resource element bundle, the actualsequence number 5 corresponds to the fifteenth physical resource elementbundle, the actual sequence number 6 corresponds to the first physicalresource element bundle, the actual sequence number 7 corresponds to thefourth physical resource element bundle, the actual sequence number 8corresponds to the seventh physical resource element bundle, the actualsequence number 9 corresponds to the tenth physical resource elementbundle, the actual sequence number 10 corresponds to the thirteenthphysical resource element bundle, the actual sequence number 11corresponds to the second physical resource element bundle, the actualsequence number 12 corresponds to the fifth physical resource elementbundle, the actual sequence number 13 corresponds to the eighth physicalresource element bundle, the actual sequence number 14 corresponds tothe eleventh physical resource element bundle, and the actual sequencenumber 15 corresponds to the fourteenth physical resource elementbundle. These physical resource element bundles are all actual physicalresource element bundles.

Since the quantity of physical resource element bundles corresponding toeach logical resource element is N/L=2, the zeroth logical resourceelement corresponds to the zeroth physical resource element bundle andthe third physical resource element bundle, the first logical resourceelement corresponds to the sixth physical resource element bundle andthe ninth physical resource element bundle, the second logical resourceelement corresponds to the twelfth physical resource element bundle andthe fifteenth physical resource element bundle, the third logicalresource element corresponds to the first physical resource elementbundle and the fourth physical resource element bundle, the fourthlogical resource element corresponds to the seventh physical resourceelement bundle and the tenth physical resource element bundle, the fifthlogical resource element corresponds to the thirteenth physical resourceelement bundle and the second physical resource element bundle, thesixth logical resource element corresponds to the fifth physicalresource element bundle and the eighth physical resource element bundle,and the seventh logical resource element corresponds to the eleventhphysical resource element bundle and the fourteenth physical resourceelement bundle. These physical resource element bundles are all actualphysical resource element bundles.

Thus, on the basis of establishing the mapping relationship between thelogical resource element and the physical resource element bundle, it isensured that different logical resource elements will not be mapped tothe same physical resource element.

According to examples of the present disclosure, the first physicalresource element bundles are interleaved, and then the physical resourceelement bundle in the interleaved first physical resource elementbundles not corresponding to any actual physical resource element bundleis marked as invalid. In the process of establishing the mappingrelationship between a logical resource element and an actual physicalresource element bundle, it can avoid the logical resource elementmapping to a physical resource element bundle with an invalid sequencenumber, and different logical resource elements will not be mapped tothe same physical resource element, thereby ensuring the reasonabilityof the mapping relationship, and ensuring that resource transmissionwill not be problematic. Furthermore, a value of a parameter in theinterleaving function is not limited, thereby ensuring high flexibilityin resource configuration.

In some embodiments, the physical resource element may be a ResourceElement Group (REG).

In some embodiments, the logical resource element may be a ControlChannel Element (CCE).

It should be noted that, in addition to a REG, it may also select othercontents as the physical resource element according to needs. It shouldbe noted that, in addition to a CCE, it may also select other contentsas the logical resource element according to needs.

As shown in FIG. 5, taking the physical resource element as the REG andthe logical resource element as the CCE as an example. If one symbol inthe time domain corresponds to 3 REGs, and one CCE corresponds to 6REGs, one CCE can correspond to REGs corresponding to symbols in thetime domain, which are symbol 0 and symbol 1, that is, 3 REGscorresponding to each time domain symbol, and 6 REGs in total.

Various embodiments of the present disclosure can have one or more ofthe following advantages.

The first physical resource element bundles are interleaved, and thenthe physical resource element bundle in the interleaved first physicalresource element bundles not corresponding to any actual physicalresource element bundle is marked as invalid. In the process ofestablishing the mapping relationship between a logical resource elementand an actual physical resource element bundle, it can avoid the logicalresource element mapping to a physical resource element bundle with aninvalid sequence number, and different logical resource elements willnot be mapped to the same physical resource element, thereby ensuringthe reasonability of the mapping relationship, and ensuring thatresource transmission will not be problematic. Furthermore, a value of aparameter in the interleaving function is not limited, thereby ensuringhigh flexibility in resource configuration.

In an example, a physical downlink control channel (PDCCH) typicallycarries downlink control information, such as uplink grant information,downlink data transmission indication, common control information, etc.,from a base station to UE. The REG typically contains a number ofresource elements. The CCE can be the basic resource allocation unit forthe PDCCH and mapped to a number of REGs. The base station can transmitthe PDCCH via a control resource set (CORESET), where the CORESET can bea set of time/frequency resources and parameters used to carry PDCCH andinclude a number of REGs (e.g., physical resource elements) that aremapped to the CCE (e.g., logical resource elements). When transmittingthe PDCCH, a physical layer (e.g., CORESET/REG) is involved, to whichcontents from a logical layer (e.g., CCE) are mapped.

In the design of the new generation communication system, the CORESETcan be the resource location where the control channel transmission islocated. The base station indicates the configuration of CORESET and theoccurrence of control signaling detection to the terminal (e.g., UE)through signaling, and the terminal can know where it needs to detectthe control channel.

A CCE can contains 6 consecutive REGs, for example, and one or more CCEscan be included in the CORESET. The total number of REGs (RB) containedin the CORESET can be N_(RB) ^(CORESET)*N_(symb) ^(CORESET).

To increase diversity gain and interference randomization, whenperforming a one-to-one correspondence between logical resource unitsCCEs and physical resource units, the order of physical resource unitscan be interleaved first, and then the mapping between CCEs and physicalresources can be performed. The physical resource interleaving mappingcan be performed with a REG bundle as the basic unit, which can becomposed of one or more consecutive REGs.
